5.4 Calibration
5.4.1 Calibration using weights, mV/V or load cell data can be done using the VNC
program. During calibration, the instrument must be set to gross weight display
(reset tare, if necessary).
For a ’legal-for-trade’ application, set the mode under -[Calibration]-[Param] to [W&M] before
starting calibration; see Chapter 5.4.20. Select [New] to go to the maximum capacity [Max] (see
chapter 5.4.7), select the scale interval and determine the dead load. Now calibrate the maximum
capacity by applying a calibration weight, in mV/V or with load cell data. After determining the test
value, the menu can be closed as described in Chapter 5.4.18, in order to save the new settings.
Calibration data can be protected by the CAL switch (see Chapter 5.1.1), which must be sealed in
the closed (write-protected) position for ‘legal-for-trade’ applications.
5.4.2 Displaying Calibration Data
Cannot calibrate!
CAL_switch is closed
When the CAL switch is closed, the following message is displayed;
only data display possible with [Param]:
Cannot calibrate!
Scale is tared
If the scale was tared, the following message is displayed, data
display with [View], reset tare with [Res.tar.], return with [Cancel]:
With [View], the calibration data can be displayed, but not changed.

The calibration data and parameters (press [Param]) are displayed in the format
entered/determined during calibration.
* After input with mV/V, the maximum capacity and the mV/V value entered are displayed.
5.4.3 Increased Resolution (10-Fold)
In the -[Calibration] menu, the weight is displayed with 10-fold resolution (also with the CAL
switch closed) when you press the key , and marked as an invalid weight with above the
weight unit. After 5 s, the display returns to normal resolution, or you can press the key to return
to normal display immediately.
